Termografía infrarroja aplicada en cúpulas históricas: identificación y análisis de sistemas constructivos

Abstract

The specific use of infrared thermography as a non-destructive technique allows the study of constructive systems in historic buildings (characterization of materials, construction layers and identification of original / restored elements). Thus, a practical application is shown in temples built between the late seventeenth and the early nineteenth century in the province of Alicante, where complementarity of thermographic images of 140 domes is analysed (along with data collected in situ, original drawings and draw up plans) as a research tool in analysis phases prior to a restoration. In conclusion, research shows how thermography is applicable to the study of different aspects such as the recognition of materials used (90.71 % solid brick, 6.43 % hollow brick and 2.86 % stone), thickness variations (75.71 % pointed shape, 17.86 % hemispherical shape and 6.43 % low shape), characterization of cracks / fissures (conservation conditions) and identification of original (96.43 %) o restored domes (3.57 %).
